These wells would be helpful in recharging aquifers at various depths below the ground surface.
It is also planned to irrigate near by avenue plants with the water stored in the sump.
The rates include transportation and installation charges for irrigating the avenue plants in the surrounding of the proposed rain water harvesting sump for reuse purpose.

49. Three Observation wells in the campus
Presently, one observation well is located near the hydro-meteorological station near the field farm to monitor fluctuations in the ground water levels for every 30 minutes using automatic water level recorder.
These water levels are monitored since 2008 and found to be 25m to 30 m deep in pre-monsoon period and 16m to 19 m in post-monsoon.
It is proposed to dig and install Three more observation wells with proper protection work.

50. Three Observation wells in the campus cont….
It is proposed to monitor daily water level fluctuations throughout the year, and to notify the fluctuations for pre and post monsoon.
It is also proposed to compare and identify the impact of rain water harvesting structures before and after execution.

51. Roof-top rainwater harvesting with a capacity of 50,000 litres and re-use
Keeping in view the availability of roof area of various buildings in JNTU campus, roof top rain water harvesting for collecting and storing rain water from roof tops of buildings and its re-use is proposed.
From the roof top, the water is diverted to disc filter unit of higher capacity.
From the filter unit, the pure water is led to leak proof storage tank.

52. Roof-top rainwater harvesting with a capacity of 50,000 litres and re-use cont…
Provision for pumping and pipe line system for taking the water from the storage tank to overhead tank is also proposed.
